Choose the Blockchain power to secure your documents

Sometimes you want to prove that a certain event happened before a certain point in time. You could use a trusted authority, which is costly and takes a lot of time. Or you could simply use the bitcoin blockchain. It is fast and nearly free.

It’s a simple principe: you send a transaction in the bitcoin network and add a comment in your transaction (via the OP_RETURN script). You have just to send the fees of transaction (0,00005 btc). The comment could be a clear message, an encrypted message or the digest of a document.

A digest is a cryptographic hash function generate from your file which is impossible to invert. The digest of a document would always be the same until you don’t modify or save it again. This is the proof that your file was exactly the same as it is today.

In embedding the digest in the bitcoin blockchain you create a timestamping which is irrefragable.
